Pop star Lady Gaga has a lot to remember New Zealand by - including some nasty bruises.

The celebrity was smacked in the head by a metal pole during Sunday's final show in her New Zealand tour, reportedly leaving her with a concussion. A backup performer accidentally struck the star with the set prop during the song Judas.

Now in Australia, Gaga posted a photograph today on Twitter of her with noticeable facial bruises and what appears to be a black eye.

"(Not sure) if I should go outside, with this clonker I may be of questionable styling," she wrote.

Earlier, Gaga thanked her fans who've tweeted their support over the injury, saying "I feel a bit woozy but a little better everyday."

Gaga's makeup artist Tara Savelo earlier wrote on Twitter: "Gaga has a concussion but she is going to be okay ... can't believe she finished the show."
